JAMES L. ONEILL, OF MACEDON, NEW YORK.

AGRICULTURAL MACHINE.

To all whom it may concern Be it known that I, James L. ONnum, a citizen of the United States, and resident of Macedon, in the county of \Vayne and State of New York, have invented ne\ and useful Improvements in rrgricultural Machines, of which the following is a specification.

This invention relates to agricultural machines, such as machines for digging potatoes and the like, in which bea.ter-inechanism is employed for the purpose of separating the adherent earth from pl ants dug or raised by the machine, or for separating potatoes or other tubers from the vines. In machines of the type in question it is common to employ heaters, or combined conveying and separating devices, comprising bars, fingers and the like which are actuated in such a manner as to agitate the material supported and carried thereby to promote the separation of the earth from the plants, or of the tubers from the vines upon which they grow. It has also been proposed to employ mechanism for this purpose in. the forn'i of a series of parallel rotatable supports or shafts provided with longitudinal rows of lingers, the supports being rotated in unison. in the same direction, whereby the material discharged upon the first lingers is conveyed from one row to another, the fingers thus constituting means for both supporting and agitating the material. .ln such previously-proposcd constructions, however, the fingers are so formed, and arranged to cooperate in such a manner, that they tend upon their supports to pinch the material between them, with the result that the apparatus becomes clogged.

The object of the present invention is to provide beater-mechanism, for an agricultural machine, consisting of a series of rotating supports having longitudinal rows of fingers, the fingers being so formed and arranged as to be free from the objection just pointed out and to transfer the material readily and freely from one row of fingers to another. To this end 1 form the fingers, and mount them upon their supports, in such a manner that the major portion of each finger extends in a direction tangential to a circle concentric with the support, but of greater diameter, this major portion pro jecting also in a direction contrary to the direction of rotation of the support. Furthermore, the tangential parts of the fingers Specification of Letters Patent.

of each row, when they assume the upright position in which they discharge the material supported by them upon a row of lingers on the next. rotating support, are substantially at right angles to the tangential portions of the latter row of lingers, while the extremities ot the latter row of fingers extend to, and pass upwardly between, the tangential portions of the fingers of the firstnicntioned row, and thus the material is stripped cleanly from the first row of lingers without any danger of being pinched between the lingers, while the lingers constitute the sole means for supporting and corn veying the material. While the advantages of this arrangement can be secured to some extent in an arrangement in which the fingers on one only of two adjacent supports are arranged in the peculiar manner which I have described, the invention, in its fullest embodiment, comprises a plurality of parallel rotating supports, each provided with lingers formed and mounted thereon in the novel manner in question.

ln the acconqmnying dra\\'ings:-Figure l is a side-elevation of a potato-digger embodying the present invention, with the nearer parts removed by a section on the line 1--1 in Fig. 2; Fig. 2 is a plan-view of the machine of Fig. 1, with the uppermost parts removed by a section on the line 22 in Fig. 1; and Fig. 3 is a detail-view, in vertical transverse section, of one of the rotatable supports, together with the fingers carried thereby.

The invention is illustrated as embodied in a machine for digging potatoes and the like, this machine having supportingand traction-wheels which support the other parts of the machine and also furnish power, in the usual manner, for actuating its moving parts. A. main frame 6 is supported by the wheels, this frame being provided with any suitable draft-device, such as a pole 7, by which it may be drawn over the ground by horses or otherwise. At the front of the machine is a plow or shovel 8 of ordinary form which, in the operation of the machine, is drawn through the ground at a suitable depth to dig or raise earth together with the potato-vines or other plants upon which the machine is to act, as shown in Fig. 1. The beater-mechanism is located in the rear of the plow, and is adapted to receive the earth and plants therefrom and to separate the earth from the plants, finally discharging the plants at the rear of the machine.

The plow 8 is shown as fixed to a cross bar 9 which constitutes a portion of a subframe having inclined parallel side-members 10 and a yoke-shaped rear transverse member 11. This sub-frame provides also the support for the beatenmechanism. As shown in Fig. 1, each side-member 10 provides bearings for a series of trunnions 12, 13, 14, 15 and 16 by which a series of transverse cylindrical supports 17 to 2-1 are journaled on the sub-frame. Each of these supports, as shown particularly in Fig. 3, is provided with four longitudinal rows of fingers 22 fixed rigidly to the support at their inner ends. From the rear-edge of the plow .8 another series of fingers 23 arojects upwardly and rearwardly,

and the fingers 22 on the foremost support 17 pass between the fingers 23 in an upward direction when the support is rotated during the operation. of the machine, so that the material raised by the plow is picked up and carried rearwa-rdly, in detached portions, by the fingers 22 on the support 17, and from them it is then passed backwardly to the fingers on the support 18, and so on until it reaches, and

is discharged from, the fingers on the rearmost support 21.

As shown particularly in Fig. 8, each of the fingers 22 has a short portion 25, adjacent the support, which is radial with respect to the latter. The finger is then bent sharply at a point 26, so that the major portion of the finger lies in a line tangent to a circle concentric with the support, but of substantially greater diameter. The supports are placed only so far apart as is neces sary to permit the ends of the fingers to pass freely by the adjacent supports, and owing to this arrangement, and to the form of the fingers, it results, as shown in Fig. 1, that when any row of fingers upon one of the supports reaches a position in which it may d1scharge the material sup ported by the fingers upon a row of fingers on the next succeeding support, the two rows of fingers meet and slightly overlap in a position in which they are at right-angles to each other, and accordingly the material may be transferred cleanly from one row of fingers to the next without any tendency to cramp between the fingers. Thusthe mate rial passes rearwardly from the foremost fingers to the rearmost fingers, and at the same time it is subjected to a continuous agitation which effectually shakes theearth f away from the vines, the earth falling freely, between the fingers, upon the surface of the ground, while the vines are carried rear wardly.

As. shown in Fig. 2, the rearmost frame is provided with only half as many fingers as the other supports. In this manner wider spaces are provided through which potatoes, or other tubers, may be shaken from the vines, while the vines are carried to, and discharged from, the rear side of the rearmost support.

The means for rotating. the supports simultaneously in the same directioncomprise sprocket-wheels 24c fixed on the trunnions 12 to 16, inclusive. The sprocket-wheels on the trunnions 12 to 15, inclusive, are connected b I sprocket-chains 27 while the trunnions L 7 15- and 16 are connected by sprocket-chains 28. The trunnions 15 are thus connected clutch-member cooperates with a toothed clutch-member 30 which is journaled coaxially with the member 29. A bearing for each clutch-member 30 is provided by 'a yoke-shaped lateral extension 31 at each side of the sub-frame, this member having a bearing-boss 82 projecting inwardly into a central recess in the clutchanember 30. Each clutch-member 30 is integral with apinion' 83 whichmeshes with a driving-gear 3 1.

Each gear 3% has an integral hub or sleeve to which one of the wheels 5 1s se'cured'by' a set-screw 36, so that the gear 34. is rotated by the corresponding wheel. To support the sub-frame firmly upon the wheels, and

maintain the several rotative parts in proper,

operative position, a stub-shaft 37 projects, from each side-member 10 of the sub-frame, through the hub 35 of the corresponding gear 254, and is provided, at its outer end,

with a head 38 which retains the hub upon,

tion in Fig. 2.

By the mechanism just described the supports 17 to 21, together with the fingers thereon, are all rotated in the counterjclockwise direction indicated by arrows in Figs. 1 and 3, and at the same .speed, by power derived from the traction-wheels 5. i

in order that the plow may be raised from engagement with the ground when the machine is to be drawn idly from place to place, and for the purpose of simultaneouslyv throwing the beater-mechanism out of operation, a hand-lever 4.0 is pivoted at 41 upon themain-frame 6 of the machine, and the forward end of this lever is connected, by a link 42, with a point on the sub-frame in advance of its axisof pivotal movement direction to raise the plow from the ground.

A toothed sector 43 is mounted on the main frame 6 in a position to cooperate with the hand-lever so as to hold the parts in adjusted position, the lever being maintained in engagement with the sector by its resiliency, and being disengaged therefrom by bending it laterally when necessary. This arrangement also permits the adjustment, at will, of the depth to which the plow enters the ground, and consequently of the amount of material removed by the plow.

In order that the movement of the hand lever, by which the plow is raised, may also interrupt the actuation of the beater-mechanism, the tilting movement of the subframe is utilized to throw the drivingclutches above described out of operation. Each of the clutch-members 29 has an annular groove which is engaged by one arm 41% of a bell-crank lever pivoted on one of the yoke-shaped members 31 on the subframe. The other arm 45 of the bell-crank lever carries a roller 46 which is adapted to cooperate with a cam-member 4L7 fixed at the rear end of the main frame 6. A coiled spring 48, connected with the bell-crank lever, normally maintains the lever in a position to hold the clutclrmein'bers in operative engagement, but when the sub-frame is tilted by the hand-lever suflicicntly to arise the plow from the ground the bellcrank levers are thus swung downwardly into a position in which the rollers 46 engage and are pressed forwardly by the cam members 47, which results in swinging the arms 44- of the bell-crank levers inwardly, thus sliding the clutch-members 29 out of cooperative engagement with the clutchmembers 30 and disconnecting the beatermechanism from the traction-wheels 5.

To maintain the sprocket-chain 27 firmly in engagement with the sprocket-wheels 2 L idler-wheels 50 are journaled upon the sidemembers 10 of the sub'frame, in position to engage each of the upper stretches of the chains 27 between their points of engagement with adjacent sprockets. The side members 10 also support mold-boards or side-walls 51 which confine the earth and the vines laterally upon the plow and the beater-mechanism.

My invention is not limited to the embodiment thereof hereinbefore described and illustrated in the accompanying drawings, but it may be embodied in various other forms within the nature of the invention as it is defined in the following claims.

I claim 1. In a machine for digging potatoes and the like, mechanism for conveying and separating earth and vines, said mechanism comprising a series of parallel rotatable supports provided with uniformly-spaced rows of fingers, each finger having its major per tion tangential to a circle concentric with, but of greater diameter than, the support and projecting opposite to the direction of rotation of the support, and the fingers in each row being long enough to extend to and between the tangential portions of the fingers of a row on the next support when the tangential portions of the two rows of fingers are at right'angles to each other, and means for rotating the supports at uniform speeds; the spaces between the fingers and above the supports being free and unobstructed so that the fingers constitute the sole means for supporting the material during the beating and transferring operation.

2. In a machine for digging potatoes and the like, mechanism for conveying and separating earth, vines and tubers, said mechanism comprising a series of parallel rotatable supports provided with uniformlyspaced rows of fingers, each finger having its major portion tangential to a circle concentric with, but of greater diameter than, the support and projecting opposite to the direction of rotation of the support, and the fingers in each row being long enough to extend to and between the tangential portions of the fingers of a row on the next support when the tangential portions of the two rows of lingers are at right-angles to each other, and means for rotating the supports at uniform speeds and in the same direction, the spaces between the fingers and above the supports: being free and unobstructed so that the fingers constitute the sole means for supporting the material during the beating and transferring operation, and the fingers on the real-most support be ing arranged at distances twice as great as those on the other supports, so as to provide wider intervening spaces through which tubers may be dropped, while the vines are supported by the fingers and discharged in the rear of the rcarmost support.
